DUs'r AND WIND GUARD.

To all whom it may concern:

Be it known that I, WARREN J. ANsoN, a citizen of the United States, residing at El Paso, in the county of El Paso and State of Texas, have invented a new and useful Dust and \Vind Guard, of which the following is a specification.

It isthe object of this invention to provide a window structure in which the sash will fit upon and interlock with, an element mounted upon the window frame, in such a manner as to prevent the passage of dust and air between the window sash and the frame; another object of the invention being to improve, and maintain the integrity of, the joint between the window sash and the window frame, thereby limiting the passage of dustand air between the sash and the frame.

The drawings show but one form of the invention, and it is to be understood that changes, properly falling within the scope of what is claimed, may be made, without departing from the spirit of the invention.

Similar numerals of reference are employed to denote corresponding parts throughout the several figures of the drawmgs.

In the accompanying drawings,Figure 1 is a sectional perspective; Fig. 2 is a transverse section; Fig. 3 is a fragmental rear elevation of the plate Fig. 4 is an enlarged transverse sectional detail of portions of the plate and sash; Fig. 5 is a top plan of the plate showing the same mounted in place; and Fig. 6 is an enlarged transverse section of the plate.

In the drawings, the numeral 1 denotes the frame of a window, and the numeral 2 the parting strips, between which the window sash 3 is slidably mounted. A plate 4 rests upon the base 5 of the window frame 1. In transverse section, this plate 4 is triangular in outline, and of suflicient height to extend nearly into flush relation with the upper face of the window sill 6.

The plate 4 is engaged, at its ends, between the parting strips 2 upon opposite sides of the window frame 1; the plate being adapted to be slid upwardly and downwardly between the parting strips. The upper face 7 of the plate 4 is inclined, so as to slope downwardly from the upper face of the window sill 6 toward the upper face of the base 5 of the window frame 1. The

outer face 8 of the plate 4 is disposed at right angles to the plane of the base 5 of the frame.

The lower edge of the window sash 3 is beveled as shown at 9, to correspond to the inclination of the upper face 7 of the plate 4, and a flange 10 depends from the lower edge of the window sash, the flange 10 being adapted to descend in front of the upright outer face 8 of the plate 4.

Secured in any desired manner to the inclined lower face 9 of the sash 3, is a resilient pad 11. This pad 11 may be fashioned from felt, rubber, leather, or like substance, adapted to the use hereinafter point- Secured to the lower face of the plate 4, and preferably located adjacent its ends, aresprings 12, preferably, although not necessarily, taking the form of arcuate resilient strips. These springs 12, pressing against the base 5 of the window frame, serve to actuate the plate 4 upwardly, and thus, when the sash 3 is moved downwardly to rest upon the plate 4, the inclined face 7 of the plate 4 will be pressed against the pad 11, thus securing a wind proof and dust proof joint between the sash 3 and the plate 4. A p

In the inclined upper face 7 of the plate 4,

there are a plurality of longitudinally eX- tended grooves 14. These grooves, 111 trans verse section, are preferably of V shape, and both of the walls 19 of these grooves are inclined at an acute angle to the plane of movement of the window sash 3, the direction of movement of the window sash being indicated by the arrow A in Fig. 4 of the drawings. These grooves 14 serve to divide the inclined upper face 7 of the plate 4 into a plurality of alined surfaces 15, against which the pad 11 is adapted to be pressed.

These grooves 14 likewise result in the formation of a plurality of abrupt abutting edges 16, and in the formation of a plurality of chambers 17, within the contour of the plate 4.

As will appear from the following description, it will be seen that the particular shape and location of the grooves 14 are 'of importance. When the window sash 3 is moved downwardly, the pad 11 will, in the first instance, be pressed against inclined surfaces 15 of the plate 4, the springs 12 eX- ercising their functions to hold the plate 4 securely against the pad 11. When the weight of the sash causes the pad 11 to be pressed firmly against the surfaces 15, the pad will be compressed over the abrupt abutting edges 16 of the plate 5, entering the chambers 17. Owing to the fact that the walls 19 of the grooves 14: are inclined at an acute angle with respect to the plane of movement of the sides 3, the pad 11, or such portions thereof as have been compressed in the grooves 14:, will expand, and interlock, as denoted by the numeral 18, behind the abrupt abutting edges 16 in the plate 4:. Thus, between the plate t and the pad 11, there is formed a uniting joint of unusual efficiency in resisting the passage of dust and air. The several chambers 17 formed by the grooves 14 serve to catch and imprison any dust which may find its way between the pad 11 and the plate 4:; these several chambers likewise serving, obviously, to prevent the upward passage of air.

From the foregoing it will be seen that I have devised a window construction adapted to be used upon passenger cars, dwellings, and other structures, in which it is desirable to have air-proof and dust-proof joints about the windows; the parts of the invention interfitting in such a way that the desired result is effected at a minimum expense.

Having thus described the invention, what is claimed is 1. A device of the class described comprising a plate arranged to be mounted upon a window frame and having an inclined upper 2 A device of the class described compris ing a plate arranged to be mounted on the base of a window frame and having an in clined upper face; a slidably mounted sash having its lower edge beveled to conform to the inclined face of the plate; a resilient pad secured to the lower edge of the sash; there being a longitudinal groove in the inclined face of the plate, the walls of the groove being inclined at an acute angle to the plane of movement of the sash, to define an abrupt abutting edge over which the pad is adapted to be compressed, the groove defining a chamber within which the pad is adapted to expand to interlock behind the abutting edge of the plate.

3. A device of the class described comprising a window frame; parting strips upon the window frame; a slidably mounted plate having its ends engaged between the parting strips upon opposite sides of the frame, the plate having an uprightouter face and an inclined upper face provided with longitudinal grooves; a sash slidable between the parting strips and having its lower edge beveled to conform with the inclined face of the plate, there being a flange upon the sash arranged to depend in front of upright face of theplate; a resilient pad secured to the lower edge of the sash and arranged to be compressed into the grooves of the plate; and a compression spring acting between the base of the frame and the plate to actuate the latter toward the pad.

In testimony that I claim the foregoing as face provided with longitudinal grooves; a' 5 my own, I have hereto afiixed my signature sash slidable into contact with the plate and having its lower edge beveled to conform with the inclined face of the plate; and a resilient pad secured to the lower edge of the i sash and arranged to be compressed into the grooves of the plate.
